以常用草坪种剪股颖为试验材料,通过室内萌发试验,研究了足量供水和限量供水条件下,不同施用量的保水剂对剪股颖种子萌发的影响。结果表明:足量供水条件下,不同用量的保水剂对高羊茅种子萌发均无影响;限量供水条件下,施用适量保水剂对剪股颖种子的发芽率、发芽势、萌发指数和根生长速度有明显促进作用。表明不同水分条件下,保水剂对剪股颖种子萌发的作用不同,且其对剪股颖种子萌发的促进作用与施用剂量有关。
In this paper, we studied the effects of water-retaining agents with different application rates on the seed germination of Scirpus horikensis under the conditions of adequate water supply and limited water supply. The results showed that under the condition of adequate water supply, the water-holding agent with different dosage had no effect on the seed germination of tall fescue. Under limited water supply, the germination rate, germination energy, germination index and root growth Speed has a significant role in promoting. The results showed that under different water conditions, SAP had different effects on seed germination, and its promoting effect on seed germination was related to the dosage.
